RING-SPINNING AND DOUBLING FRAME.

SPECIFICATION forming part of Letters Patent No. 501,737, dated July 18, 1893.

Application filed March 9, 1893. Serial No. 465,253. (No model.) Patented in England March 8, 1884, No. 4,566-

To aZZ whom it may concern.-

Be it known that we, GEORGE SHEPHERD and HENRY MIDGLEY, subjects of the Queen of Great Britain, residing at Bacup, in the county of Lancaster, England, have invented certain new and useful Improvements in or Applicable to Ring-Spinning and Doubling Frames, (for which we have received Letters Patent of Great Britain, No. 4,566, dated [0 March 8, 1884;) and we do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to the means which are employed in ring-spinning frames and doubling frames for the purpose of preventing or obviating what is known as the ballooning of the threads being spun or twisted in such frames, and it consists in certain improved constructions and arrangements of mechanism for independently supporting and actuating or moving up and down a separate rail, or the like, which is located adjacent to a ring-rail and carries the anti-ballooning or yarn-separatin g arrangement or device which may beemployed for preventing the said ballooning.

In our application for United States patent,

3o filed March 9, 1893, Serial No. 465,252, we have described and claimed an improved anti-ballooning or yarn-separating arrangement consisting of a separate thin metal plate or rail, of any convenient length, or extending the 5 entire length of the side of a ring-spinning or doubling frame if desired, this thin plate or rail being located above the ring-rail and having formed therein a hole of sufficient sizefor each spindle, the holes being concentric with 40 the spindles and rings, and a narrow groove or slit leading into each hole, at about a tangent to the circle of the hole, being formed in the plate or rail for the thread to pass through. As isindicated in the drawings form- 5 ing a part of this specification, we may employ this arrangement in connection with the supporting and actuating mechanism hereinafter presented, or; in lieu of the former, we may employ equivalent anti-ballooning or yarn-separating devices, that is to say, other arrangements having suitable known forms and arrangements of devices located beside the spindles in a position to operate by interfering with the tendency of the yarn-balloons to expand during the rotation of the spindles, such, for instance, as the known arrangements in which anti-balloon rings, wires, plates or other guards are mounted on a rail whereby they are sustained in proper positions adjacent to or between the spindles.

In reducing our invention to practice, we mount the anti-ballooning arrangement on rods that will slide freely up and down, and we actuate these rods by the improved and novel means which we presently shall proceed to describe. In the preferred embodiment of our invention we actuate the said rods by self-acting means whereby the anti-ballooning arrangement is caused automatically to move at the same time as the ring-rail and in the same direction as the latter, but at a difierent speed, the distance between the anti-ballooning arrangement and the ring-rail being reduced as they rise.

Our invention first will be fully described with reference to the accompanying drawings, and then will be particularly pointed out and distinctly defined in the claims appended to this specification and forming a part hereof.

In the drawings, Figure 1 isaview in front elevation showing part of a ring-frame havin g applied thereto the preferred embodiment of our invention.

Fig. 5 is a view in plan of certain of the parts that are represented in Figs. 3 and 4, showing the manner of transmitting motion to the anti-ballooning arrangements on, both 5 sides of the ring-frame or doubling-frame. Fig. 6 is a view in front elevation showing an arrangement of devices that may be employed in accordance with a further modification. Figs. 7 and 8 are views of details of I00 the modification that is represented in Figs. 3 and 4. Fig; 9 is' a view'in plan showing partof the anti-ballooning plate or rail that may be employed if desired, and also showing portions of the ring-rail and spindle-rail. Fig. 10 is a detail view in elevation. Figs. 1-1, 12, 13, 14 and 15 are views showing modifications 1 hereinafter presented.

The front rolls of a ring-frame are shown at e, the thread-guides or guide-wires at d, the finger-boards at d, the spindles at c, the bobbins mounted thereon at c, the rings at b, the travelers mounted on the rings at Z1 the ring-rail at b, the pokers whereby the ringrail is sustained at W, the spindle-rail at A, and the lower or guide-rail at A All of these parts are of any known and desired character and construction.

At a, see particularly Fig. 9, is shown the form of anti-ballooning arrangement hereinbefore mentioned as one of the forms which may be employed, and covered by our application,aforesaid. Ashereinbefore indicated, it consists of a thin plate or rail of metal with a circular hole a cut out ofitfor each spindle, each hole being concentric with its spindle c and the'correspondingring b, and a little larger in diameter than the inner diameter of the ring so that a full cop or bobbin 'will pass' clear through the hole a. The spindles extend upwardthrough the holesa, andthus the anti-ballooning or yarn-separating arrangements which the plate or rail or provides are located beside the spindles ina position to operate by interfering with the tendency of the yarn-balloons to expand during-'the'rotation of the spindles. As shown in Fig.9, the front edge of the plate or rail is formed with a series of rounded swells and re-entrant angles and there is a slit 0, through such front edge leading from each of's'uch angles to the adjacent hole a to allow the thread to pass, this slit a, beingmade at about the opening of the slit and will not escape.

- angle lengthwise of the ring-rail.

If the threads rotate in the direction opposite to that shown by the arrow, the direction of the slitswill have'to be reversedaccordingly. The anti-ballooning arran gementa is mounted at the upper ends of the sliding rods a,which slide up and down through the guides-a A common and well-known mode of actuating the ring-rail is by levers or arms on shafts or axes placed across the frame, or at a right Our invention isshown in Figs. 1 and 1 combined with this well-known form of actuating means. At f,f, in the said'figure are shown the said levers or'arms', and atf, f, are shown the said shafts or axes thereof. A- stud or pin f on the endof each arm f acts as usual against theunder'side 'of the foot or shoe b on the lower endof the corresponding poker b actuation of the cross-shafts.

"ring-rail.

from the said plate or rail.

At f, f are shown upwardly extending arms onthe cross-shafts f, f, the said crossshafts,f,f, and their arms, f,f, and f f constituting what may be designated as rockers, and at b,b, are connecting-rods by which .the saidarins fflf are connected with each other andwith copping-motion mechanism of any suitable known kind to provide for the We connect or engage the lower ends of the rods a, a, in suitable manner with the cross-shaft arms f,

as by means of a pin a on each rod entering a slot f extending lengthwise of the arm, whereby the anti-ballooning arrangement a is caused to rise and fall in unison with the Each rod a is actuated from a portion'of the correspcnding cross-shaft arm f which is intermediate the axis on which the said armturns and the point at which motion is transmitted from theiarm to the corresponding poker b In consequence of separately operating, the anti-ballooning arrangement from the cross-shaft arm through means rangement in such manner as to cause it to rise-and fall ata reduced speed and to areduced extent compared with the ring-rail or copping-rail, the distance between the antiballooning arrangement and the ring-rail being reduced asthe ring-rail rises.- The illus- {trated connection of the rod 0/ with the cross- ,shaft arm f is 'pos'itive,and' causes movement: to-be transmitted positively to the rod a in both directions, soas to preventithe said :rod from sticking in its guide a and from failing to descend at the proper time.

The poker b is provided with a stop which 'isconnected therewith and serves to arrest the descent of the ring-rail when, in being .lowered by hand after the bobbins or cops have been wound to the desired extent, the

; ring-rail has descended to the point necessary to be reachedthereby in order to permit the doffing to be effected. In the drawings this :stop is constituted by the collar 5 that is applied to the upper portion of the poker and held at the desired height thereon by means of a clamping screw I) which passes through the side of the collar and takes bearing by its end against the surface of the poker. the descent of-the ring-rail has been arrested After by the contact of the collar 11 with the top of the guide 19 or other stationary part,.and the lowest position of the ring-rail has been determined thereby, the arm f may be turned still lower, as indicated in Fig. 1, to depress the plate or rail a sufficiently to permit the dotting to be effected without interference The additional movement ofarm f may be occasioned by pressing thereon, or by moving any arm or .lever connectedwith therods b and any suit- IOC ITO

able means may be employed for holding the arm f in a depressed position until after the doifing has been completed.

A convenient means of giving to the shaft f the additional movement required for lowering the anti-balloon plate or rail from the position shown in dotted lines at a? to the position shown in full lines in Figs. 1 to 3, is shown in Figs. 3 and 10. In these figures there is shown at g a handle mounted to turn loosely on shaft f, and held in place at the side of collar 9 fast on the shaft by means of a collar g which also is fast on the shaft. The handle 9 has a pawl g pivoted thereto, and the disk g is formed with a notch g with which the pawl g is adapted to engage. After the ring-rail has been lowered, as just above described,the handle g may be grasped and drawn forward, and thereby, in consequence of the engagement of the pawl g with the notch g in the disk 9 the shaft f may be rotated sufficiently to lower the anti-balloon plate or rail a from the position indicated at at to the position shown in full lines. When the shaft f has been turned thus to the required extent, a pawl 9 pivoted on a stud on the framing or on a bracket carried thereby, enters a notch g in either the disk g if desired, or a second disk g also made fast on the shaft f. Thereby the parts are retained in the desired position during doffin g. When that operation has been completed, the retaining pawl g is released and turned back out of the way, and the shaft f is allowed to go back to its normal position,the pawl g on the handle 9 being turned back also so as to be out of the way, and not catch in the notch or notches in the disk 9 when the copping mechanism is at work. The handle g rests against a stud g projecting from the framing or a bracket attached to it when the copping motion is working.

In place of giving the extralowering movement to the arm f and the anti-ballooning arrangement in the manner just described, it may be secured by forming the rod or conneetion b between the copping mechanism and the first lever or arm f with a slot- 19 for the reception of a pin 1) on the said arm f, as shown in Fig. 2, the said slot having an offset portion or. notchb at the right-hand end thereof in the said figure, in which offset or notch the pin b normally remains engaged during the regular workin g of the ring-frame. By lifting the end of rod 12 so as to withdraw the notched part thereof from the pin b the said pin is released and permitted to pass to the opposite end of the slot 1) which allows the anti-balloon arrangement to descend-to the additional extent that is required to permit the doifing to beeffected. By moving the arm f in the reverse direction the antiballoon arrangement will be raised again. to the proper height above the ring-rail, and the notch may then be permitted to pass down upon the pinb In the construction that is represented in Figs. 3, t, and 5 the rods a, supporting the 'rail or plate a or its equivalent are actuated by rockers in the form of bell-crank levers h, 72, each lever having its fulcrum h on a bracket A secured to the rail A The arms h 72. of the said levers are connected together by a wire or rod 72, passing from one of said arms to the other thereof, the said rod being in two parts united by a right-and-lefthanded screw coupling h whereby to adjust the position of the left-hand lever or levers h and the level of the plate or rail aor its equivalent. The end of the arm h of each lever h is or may be formed with an eye It swiveling on a pin it passing through a hole in the end of the arm, as shown in Figs. 7 and 8. The rod or wire h connecting the arms h 71, of the levers h, h, is, in this case, made to pass through the eye h and each length of rod has a screw-thread at the ends and the lengths are coupled together by a screw-nut coupling 71.

the latter having locking nuts h, h. There is also a screw-nut hi 71. on each side of the swivel eye h so that each bell-crank lever it may be adjusted separately without disturbing the adjustment of the other levers.

The levers h, h, shown in Fig. 3 may be moved, for the purpose of moving or adjusting up and down the plate or rail a or its equivalent,.by various means. The arrangement shownin Fig. 6 may be employed. In

the. latter figure, the rod h is shown connected at its end Withanuti mounted upon ascrewshaft '5 held in suitable bearingsyin the end of the frame A, the said nut being prevented from revolving with the screw by a pin i extending from it, which moves freely in a slot 11 in the rail A or in a part carried by that rail. When the screw-shaft t' is rotated by the hand-wheel t the nut t", and consequently the plate or rail a or equivalent arrangement, will be adjusted into any required position. The arrangement shown in Fig. 6 may. be duplicated on the opposite sides of a frame, or the levers h on both sides of a frame may be connected with one such arrangement.

In Figs. 3, 4, and.5, we have shown-a selfacting means whereby the levers h, 72, may be operated tomove the plate or rail 0., or equivalent arrangement, up and down. At f is a shaft extending lengthwise of the frame at one side thereof, and connected in usual manner with the pokers of the ring-rail. practice, the said shaft is caused to rock by suitable means, and thereby the usual movements of the ring-rail or copping-rail are 00:-

casioned. The arrangement described will be recognized as one. pertainingto an ordinary form of ring-rail actuating mechanism. At is shown a cam of suitable shape, mounted upon the shaftfand act-ing upon a bowl the rail A The other end of the said short chain is connected with the rodor wire-h onthe sameside of the frame, and thus,.as the shaft f and camj oscillate, the plate. or rail a, or equivalent arrangement, will be moved up and down accordingly. When the shaftf is turned by hand, asfit may be to :lowerthe ring-rail to the positionfor doffing, the shape and arrangement of the camj permit of the plate or..rail a, or equivalent arrangement, being lowered alsoto the proper doffing position. Instead of a disk-cam j being em.- ployed, as-shown, a drum cam j may be used, as shown in'Figs. 11 and 12, the action of such cam-being in a line with the-shaft f, and when this latter form of camis used the lever j will be changedin position accordingly, and the wire'or rodh may be connected directly with the end of the said lever. The pulley 7' may be a pulley with .three grooves, and the short lengths of jointed chain in each groove may beattached thereto, onechain 3' extendingv between the lever 7 and its groove, saythe middle groove, another chain 7' extendingfrom the lower groove to the wire or rod 71. on one side of the frame, and another 3 extending from the third groove to and around a pulley 7' on the other side of. the frame, where it is connected with the wire or rod 11. on the latter side. Thereby,- the anti -.ballooning arrangements on both sides. of the frame may be simultaneously actuatedfrom the same cam. It is obvious that inplace of chains and-pulleys levers may be .used, and a shaft may be used to connect the mechanism ofv one-side of the frame with that on the other side, if desired.

Figs.13 and 14 show one of the arranges mentsof levers and-connections that maybe employed asjust mentioned, if desired. It is to be understood, however, that no particular form and arrangement of the levers and their connections is regarded by us as especiallyiniportant. Fig. 13 is a plan view illustrating sufficient. to make clear the modification intended to be represented therein. Fig. 14 is a partially sectional elevation of the parts which are shown in Fig. 13. At 3' f, in ,these. figures, are represented horizontal levers having their outer ends joined or connected to the wires or rods, 7?, h and their inner ends connectedby short rods or links, 7' f, to a cross-piece or head, j", on a sliding rod,j that is joined by a short rod or link, 1, to the lever, j, the latter being actuated by a drum-cam, j, on the shaft, f.

Fig. ,15 is a sectional elevation showing an arrangement in which a shaft is used to connect the mechanism on one side of the frame with that on the other side, if desired, as stated above.- In this figure the levers, j, j, on opposite sides .of the frame are made fast upon the rock-shaft,j one of the said levers,j, being engaged and actuated by the drum-cam, j, on the shaft,f.

In place of lowering the anti-balloon plate or rail, or its equivalent, in the arrangement described and shown in detail .in Fig. 2.

tioned.

shown in Figs, 3, 4 and 5, by turning the shaft f by hand, the lowering maybe effected by a lengthening and shortening, or releasing, arrangement onthe order of that hereinbefore In this case, the rod 5 of Fig. 2 would be the first length of wire or rodh 'between the le- Verj and thefirst arm h We donot lay broad clai m herein to mounting the anti-ballooning plateor rail on rods, and operating thesame by means whereby it is caused to move in unison-with the-ring-rail but at a reduced speed, and through'a traverse of diminishedextent, or to a stop for determining the extent of the descent of thering-rail or copping-rail', or to the devices shown in Figs. 3 and .10 for turning the shaft f by hand,.for we have laid such claim in our application for patent hereinbefore men- The particular modifications which are shown in Figs. 3 to 8 of our drawings,-have been claimed specifically in our other application for patent for improvement. in ringspinning and doubling frames filed March 9, 1893,;Serial-No. 468,25 We, therefore,qdo
